Engis CBN superabrasive grinding wheels are available in a variety of sizes and styles, both plain and formed to specific contours. These grinding wheels are designed primarily for grinding such materials as: high carbon; high chrome; high speed steels, such as M2, M3, M7 and T15; die steels, such as: D2, D3, HB, A & O; alloy steels (harder than 50 Rc); nickel and cobalt base super alloys; titanium; stainless steels, etc.

Electroplated CBN grinding wheels offer substantial benefits in grinding exotic alloy steels. Since the CBN crystal resists dulling much better than conventional abrasives, it provides stress-free, cool cutting action throughout its long life. The crystal tends to be self-sharpening as cutting stress increases. The mono-layer wheel structure requires no truing or dressing throughout its life, thereby eliminating truing tool cost as well as non-productive wheel truing time.
